Abstract (en)
A composition and method for forming elastomeric pressure sensitive adhesives comprising a mixture of (A) a xylene-soluble resin copolymer of 0.6 to 0.9 triorganosiloxy units per SiO4/2 unit and having less than 0.7 weight percent silicon-bonded hydroxyl units, (B) a polydiorganosiloxane fluid endcapped with silicon-bonded hydroxyl groups and having a viscosity of from about 50 to 300,000 cP. at 25 DEG C., an organosilicon compound containing an average of more than two silicon-bonded alkoxy groups per molecule, and a condensation catalyst. The cured elastomeric pressure sensitive adhesives formed from these compositions are useful as medical adhesives, such as those used for ostomy seals.
